Anglian Water is urging people to take extra care to make sure they’re protected from bogus callers.
The advice comes as the longer, warmer summer evenings mean the number of attempted break-ins to business locations, like Anglian Water sites, generally increases.
The water company works hard to prevent these intruders, thefts and invest in tighter security but they are still targets for crime.
Recently Anglian Water branded clothing was stolen, hence the need for extra vigilance.
The water company is asking local communities to be vigilant and carefully inspect ID cards of any doorstep callers.
